SimplEQ Processor Plugin (AUv3) SimplEQ is an audio effect plugin that can run standalone, or in any AU compatible host application such as Logic Pro or GarageBand. To configure audio settings in standalone mode, tap the Settings button. Please note that the input will be muted by default to avoid nasty feedback! Overview SimplEQ is a very simple EQ - the clue is in the title! For those times when you don't need "surgical precision" and seemingly endless parameter options to tweak, SimplEQ might be just the thing for "broader brushstroke" EQ tweaks. SimplEQ is also very kind to your CPU. The frequency bands have been tuned so that they overlap and interact slightly, giving a surprisingly flexible range of tonal sculpting. Whether you're doing a quick rock mix master, or simply want to warm-up or add presence to a track, SimplEQ might get you there - fast and simple! For a super-simple lightweight "mastering suite" you could partner SimplEQ with the LevLr2 dynamics processor. Controls Active - Toggles the EQ On or Off. You can use this control to A/B your settings with the original signal and this will fade gradually between the two with no distracting pops or clicks! Each of the frequency bands can be cut or boosted by +/-6dB and because they overlap, they are very interactive, so use your ears, and dial-in to taste! Sub - Adjusts extremely low frequencies centred around 50Hz. Bass - Adjusts low frequencies centred around 100Hz. Lo Mid - Adjusts low midrange frequencies centred around 250Hz. Hi Mid - Adjusts high midrange frequencies centred around 1KHz. Treble - Adjusts high frequencies centred around 5KHz. Presence - Adjusts very high frequencies centred around 10KHz. Out - Applies a final stage gain trim to the output at the very end of the internal signal chain, between -24dB and +6dB.

• AUv3 plugin to modulate and sequence MIDI instruments and modular hardware • Outputs MIDI and analog CV simultaneously for integrated hybrid setups • Fully functional in software-only environments with full MIDI support • Converts LFOs, MIDI notes, pitch, and control changes into control voltages • Includes two LFO generators with random spline, cross-modulation and syncing • Integrated envelope follower to track audio input or sidechain signal • Six FLO(W) processors for combining and shaping signals with math and logic • Each FLO supports 18 inputs with individual polarity, divider and multiplier • Multi-out support, built-in waveform viewer, Audio FX, and MIDI FX • Advanced Responsive Design, portrait and landscape views • Universal Purchase: AUv3 for iOS (iPad/iPhone), macOS and Vision Pro FAC Polyflo is an AUv3 plugin for modulating and sequencing MIDI instruments and modular gear via control voltage. It outputs MIDI and analog CV simultaneously, making it well-suited for hybrid setups that combine digital and analog equipment. The plugin includes two LFO generators offering 10 waveforms, including classic shapes and random spline, with support for cross-modulation and syncing. It also features an envelope follower that tracks audio FX input or an external sidechain. The generated signals, together with the host clock and MIDI input, are fed into six independent FLO(W) processors. These processors combine, shape, and route inputs using math operations, conditional logic, and comparators. Each FLO includes individual polarity, division, and multiplication controls, providing deep and flexible modulation that balances chaotic creativity with precise timing. Each FLO processor output is connected to its own output bus, enabling easy integration with hardware via DC-coupled audio interfaces like the Expert Sleepers ES-9. For simpler setups, FLO outputs can be routed to the stereo output. FAC Polyflo can also convert MIDI notes, pitch, and control changes into control voltages, making it a powerful MIDI-to-CV solution. If you prefer to work exclusively with software, the plugin runs smoothly in software-only environments with full MIDI support, making it equally suited for purely digital workflows. FAC Polyflo works as both an Audio Unit FX and MIDI FX, featuring a clean, touch-optimized interface with precise control and waveform visualization. It’s available as an AUv3 for iOS (iPad/iPhone), macOS, and Vision Pro, and requires a compatible AUv3 host app to run. This is an AUv3 Effect and requires a compatible host to work The documentation is available at fredantoncorvest.com/FAC_Polyflo.html
